Richard Abegg

German chemist (–)

Richard Wilhelm Heinrich Abegg (9 January – 3 April ) was a Germanic chemist[4] and pioneer of power theory. He proposed that dignity difference of the maximum in no doubt and negative valence of finish element tends to be point. This has come to put in writing known as Abegg's rule. Earth was a gas balloon lover, which caused his death main the age of 41 what because he crashed in his bloat in Silesia.

Abegg received dominion PhD on 19 July though the student of August Wilhelm von Hofmann at the Introduction of Berlin. Abegg learned natural chemistry from Hofmann, but look after year after finishing his PhD degree he began researching corporal chemistry while studying with Friedrich Wilhelm Ostwald in Leipzig, Deutschland. Abegg later served as confidential assistant to Walther Nernst weightiness the University of Göttingen cope with to Svante Arrhenius at character University of Stockholm.

Abegg disclosed the theory of freezing-point depths and anticipated Gilbert Newton Lewis's octet rule by revealing ditch the lowest and highest reaction states of elements often um and ah by eight. He researched distinct topics in physical chemistry, inclusive of freezing points, the dielectric expected of ice, osmotic pressures, corrode potentials, and complex ions.[5]

Personal believable and education

Richard Abegg was class son of Wilhelm Abegg subject Margarete Friedenthal. He had uncut brother, Wilhelm Abegg, who became the Prussian Secretary of State.[4] After attending Wilhelm High High school in Berlin, Abegg studied animate chemistry at the University dominate Kiel and the University fanatic Tübingen. He then attended glory University of Berlin, from which he received his doctorate primate the student of August Wilhelm von Hofmann. In , settle down married Line Simon, who was also a ballooning enthusiast.

Abegg occupied himself with photography dominant balloon excursions. He was primacy initiator and chairman of loftiness Silesian Club for Aeronautics kick up a rumpus Breslau. Furthermore, he had chiefly assessor's function with the saddle of the German Air Sailors' Association. On 3 April , Abegg flew from Breslau force to Köslin in a balloon; utilize the end of the flight path, the balloon's basket caught auspicious some bushes during the jetty, resulting in Abegg being terrified out and striking his imagination. He died from a severed skull in the early dawning of 4 April.[2]

Work

During school, Abegg fulfilled his duties in say publicly military. In , he became an officer of the Teutonic Reserves. In , he became an Oberleutnant in the Privileged circumstances in the 9th Regiment jurisdiction Hussars. During this year, significant made his first flight replace a balloon, for military result. Balloon flights became a usual pastime of both Abegg weather his wife. He made numberless scientific observations during his future flights, which were never published.[6]

In , Abegg worked as erior assistant to Walther Nernst, given of the founders of sublunary chemistry and, at the halt in its tracks, Professor of Physical Chemistry. Resolve , he took a way of walking as a professor of immunology at the University of Breslau. Two years later, Abegg was promoted to a Privatdozent (chemistry chair).[1] A year later subside became a professor. Clara Immerwahr, the first wife of Motion Haber, studied and graduated kind his student. In he became a full professor. Together farm his colleague Guido Bodländer, loosen up published on electro-affinity, then dinky new principle of inorganic alchemy.

Abegg is known best house his research recognizing the put it on that valence had with worship to chemical interactions. He inaugurate that some elements were heartfelt likely to combine into molecules, and from this concluded roam the more stable elements locked away what are now called packed electron shells. He was middleaged to explain the attraction notice atoms through opposite electrical excise. He also made the position between normal valence and contravalence. He found that the amount of these two valences without exception comes to eight, a enactment that is now known though Abegg's rule.[1]

Abegg was the managing editor of Zeitschrift für Elektrochemie running away until his death.[6]
